<h4 class="subsection">3.6.1 Output Section Description</h4>
<p>The full description of an output section looks like this:
</p><div class="smallexample">
<pre class="smallexample"><var>section</var> [<var>address</var>] [(<var>type</var>)] :
  [AT(<var>lma</var>)]
  [ALIGN(<var>section_align</var>) | ALIGN_WITH_INPUT]
  [SUBALIGN(<var>subsection_align</var>)]
  [<var>constraint</var>]
  {
    <var>output-section-command</var>
    <var>output-section-command</var>
    &hellip;
  } [&gt;<var>region</var>] [AT&gt;<var>lma_region</var>] [:<var>phdr</var> :<var>phdr</var> &hellip;] [=<var>fillexp</var>] [,]
</pre></div>

<p>Most output sections do not use most of the optional section attributes.
</p>
<p>The whitespace around <var>section</var> is required, so that the section
name is unambiguous.  The colon and the curly braces are also required.
The comma at the end may be required if a <var>fillexp</var> is used and
the next <var>sections-command</var> looks like a continuation of the expression.
The line breaks and other white space are optional.
</p>
<p>Each <var>output-section-command</var> may be one of the following:
</p>
<ul>
<li> a symbol assignment (see <a href="Assignments.html#Assignments">Assignments</a>)
</li><li> an input section description (see <a href="Input-Section.html#Input-Section">Input Section</a>)
</li><li> data values to include directly (see <a href="Output-Section-Data.html#Output-Section-Data">Output Section Data</a>)
</li><li> a special output section keyword (see <a href="Output-Section-Keywords.html#Output-Section-Keywords">Output Section Keywords</a>)
</li></ul>
